VI-1 Method Detection Limit (MDL) and Data Reporting 

For MATES III, guidance for determination of the Method Detection Limit (MDL) and data 

reporting was taken from the U. S. EPA’s National Air Toxics Pilot City Monitoring Program. 

The MDL, as defined in 40 CFR Appendix B, Part 136, “Definition and Procedure for 

Determination of the Method Detection Limit” was used. The MDL is defined as the minimum 

concentration of a substance that can be measured and reported with 99% confidence that the 

analyte concentration is greater than zero and is determined from analysis of a sample in a given 

sample matrix containing the analyte (EPA, 2001) 1

The AQMD Laboratory used this MDL determination method for the analyses conducted. It 

consists of seven replicate analyses of a sample containing the analyte of interest at a level not to 

exceed five times the projected MDL. A standard deviation is determined using results of the 

analysis. The standard deviation times 3.14 (from the Tables of Student’s t Values at the 99% 

confidence level) is the reported MDL. 

It was recognized by the Science Advisory Board (EPA, 2001) that just because a value is below 

the MDL does not mean the Laboratory has not been able to measure a value, but rather the 

measurement has less reliability than others above the MDL. From this study, it became the 

convention for MATES III to report every value, even those below the MDL. These values were 

flagged as being below the MDL but above the Limit of Detection (LoD). For analytes that had 

concentrations that were below the LoD, no concentration is ascertained in the analysis; and the 

data are reported as zero. 

Particulate metals were measured by X-Ray Fluorescence (XRF), which exposes the Teflon 

sample filter to X-rays to induce excitation and subsequent florescence of the metals. For these 

measurements the statistical counting error of the detected pulses is calculated. An advantage of 

using this technique is that the analytical uncertainty can be calculated every time an analysis is 

performed. The detection level can also be determined during the calibration process using 

single element thin film calibration standards. For data reporting, the detection level is 

substituted for negative or zero values. Negative values appear in some instances because 

occasionally, the Teflon filters used for background subtractions are lower than the sample filter. 

An uncertainty value is also reported for each data point. 

In calculating the average concentrations, the reported analytical values are used. Other 

reporting conventions include reporting a value equal to 1⁄2 the MDL for all values below the 

MDL. However, this can lead to potential biases in calculating average values. 

To illustrate the effect of using 1⁄2 the MDL compared to the analysis value, three examples are 

presented. The following figures show the frequency distributions of reported data for benzene, 

1,3-butadiene, and vinyl chloride.

MATES III Final Report

Appendix VI-3 

The chart for benzene shows an example where very few data are below the MDL, and there is 

little effect on the average of using 1⁄2 the MDL for data that are lower than the MDL. 

The chart for 1,3 butadiene shows a considerable number of values below the MDL. Here using 

1⁄2 the MDL would bias the average upward. This becomes more of a concern as ambient 

concentrations decrease over time as a result of emissions reduction and may give an 

inappropriate view of the actual trends in levels. 

Vinyl chloride gives an example of a substance where very few data are at detectable levels. 

Clearly, in this case, using 1⁄2 the MDL would bias the average high.
